The LG01-2000A090 is a Liquid Flow Switch and Bubble Detector enables detection of flow of liquid in the range of ml/min. The output signal is 5V when the flow rate is higher than the specified flow switch point and 0V below this limit or when air or bubbles are found inside the sensor flow channel instead of liquid. Excellent chemical resistance and bio-compatibility are ensured. The flow path of the LG01 liquid flow switch is formed by a simple and straight glass capillary.
